Reflux disease is caused when the valve at the top of your stomach no longer closes properly. This allows the acid in your stomach to reflux, or flow back up your throat.

The acid, while in your throat, causes the common symptoms of heartburn. It can also cause difficulties swallowing, hoarseness, a persistent cough, swelling, burning, and even sleeping problems.

Treating acid reflux begins with lifestyle modifications. Avoiding foods that trigger heartburn, and changing the position you sleep in are two easy ways to reduce uncomfortable symptoms. Maintaining a healthy weight and not eating late at night can also reduce the symptoms of acid reflux.

After these changes, over-the-counter antacids and other medications can help.
